y=x+3

2x + x + 3 =6
3x + 3 = 6
3x = 3
x = 1

-1 + y = 3
y = 4

2(1) + y = 6
2 + y = 6
y = 4

Answer:

$\sf\longmapsto \: x = 10$

Step-by-step explanation:

Subtract 7 from both sides:

7−5x−7=−43−7

Simplify:

−5x=−50

Divide both sides by −5:

$\sf\longmapsto \: \frac{ - 5x}{ - 5} = \frac{ - 50}{5}$

$\sf\longmapsto \: x = 10$
